I personally love Kaspersky Internet Security 2013 and I have a 10-pc license. My living room PC (HTPC) doesn't have any AV as of now but I plan to do a Win8 Pro clean install this week because it's the only one in my house with Win7. Can I activate the Antivirus, do a clean install and use the same license again?

I installed it on my brother's laptop with the following code: 0GPPDC3

The license expires in 677 days which is 1 year, 10 months, and 12 days. The other codes only give you 365 days.

I just clicked on "365 days left" and it lets you use a different serial, put in the 677 day serial now i have 677 days left instead of 365 days

Can we use the license again when we reformat?

Perhaps it generates a "complete license" once you register it using on these promo codes. I will try to activate it and see if I can use it again when I format the HTPC this weekend. Will post any findings.

Make an account after installing Bitdefender and activating a key. Once you do that, your computer will show up in your MyBitdefender account. It should recognize your computer after you format. I'm not 100% certain about this though.

EDIT: Actually, I think it doesn't necessarily tie to one computer. Instead, it can be used on any computer as long as it's one at a time. It may be different with these keys though. The OP stated that the keys must be activated within 30 days so I don't know what will happen after the 30-day period ends.

Mine won't even update, just stalls at 0.00kb suppose the update servers are getting hammered

Mine worked earlier. Did you try clicking the small "auto update" button after clicking "update" as mine didn't do anything until i did that. Just updated the internet security just now, downloaded a 3.75mb update.

As Anaron suggested, be sure to register for the account. In your account, there's a way to remove the device you have tied to your BitDefender account, so I'm pretty sure you can install this again just fine and re-tie the device back to your account, if it doesn't recognize it after the format.
